To all whom/it mag concern:

Be it known that I, JULIUS L. ALLEN, a citizen of the United States, residing at VVheatland, in the county of Yuba and State of California, have invented new and useful Improvements in Farm-Tractors, of which the following is a specification.-

This invention relates to farm tractors, and it has for its object to produce a traction engine of simple and improved construction in which the motor from Which'power is derived, as wellvas the means for transmitting motion to the main drive wheel, shall be located entirely within the'perimeter of suchdrive wheel, the latter constituting; a cage or housing for such motor and mechanlsm.

A further object of theinvention is to produce; a traction engine of the character described having a single drive wheel" and motor means for driving the same, thereby disnensing with the use of and" necessity for differentials and other complicated and expensive transmission means. v

A further object, of the irwentien is to produce a simple and improvedktnactiorr eng-ine: of the-type described; wherein provisionis made for utilizin-gfthe motor as a stationary! engine for driving machinery of various kinds,

With these and other endswinevievw which will; readily appear. asthenaturez of. the; invention. isybetter; under-stood, the; same'acom sists in; theimprovediconstructionrande novel arrangement and combination of 1, parts which will be hereinafter fullydesoribed-and particularly pointed; out in,=tl1eclaims-;.

In the accompanying drawings has: been illustrated a simple and preferred form of theginvention, it being,-choweven, understood that-no limitatiomisanecessarily/made to" the precise structural, details-therein exhibited, but; that changes, alterations w andimodifica tionsy within the soopeeofjthe': claims mayibe I resortedito ,whenedesirede In theedrawings i Eigurdli sides elevation; ofa-jtracti'on engin constructedin; accordancer with-ithe invention;,; Eig. i2g isealto langviewe;

Fig. 3 is a transverse sectional view taken on the line 3 8 in Fig; 1.

Fig. 4 is a detail View on a larger scale, partly in plan and partly in'section; of the counter shaft and relatedparts for driving stationary machinery;v

Corresponding parts in the several figures aredenoted by like characters of reference.

The frameof the machine, which has been shown as being mainly of rectangular form, may be constructed of structural steel, iron, wood or of any desired material or coiii'bination of materials, said frame having been shown as including in its construction side members 15,15,front and rear end members 16, 17 transversely disposed braces 18, 19 near the front andrear ends, respectively. A seat 20 for theoperator is su'ppor'ted at the rear end of the frame, The ground wheel or driving Wheel, which is generally designated by B, includes in its construction a hub-21 and a: relatively wide rim 22, the hub having flanges 23 that are connected with the rim by spokes 24. The rim is of a width greatly exceeding that of the hub, which latter is positioned with one of its flanges: substantially in the plane of one of the side edges of the rim 22, the other flange of the hub being positioned in a" plane'intermediate the side edges of the rim; the posi tionof the hub may, therefore, be described asmbein gadjacent-to one side of the rim. The hub isfixed on an axle 25- w-h-ichi is mounted for rotation-inboxes or bearings 26' atlthe *upper' ends of pedestals" or brackets 27 rising-from the side memberslo, 15 of the frame, which latter will thusbe practically suspended 'from the axle. V

Supported within the-niain frame is: an auxiliaryframe, generally; designatedby C, said; auxiliary frame having side-members, one of which, 26 isfirm'ly connected by m'eansofclips-G with the sidegmeniber 15"01? them-11in frames The other side--memberg 2i, of-ithefrauxiliary f'frame 'hasian upwardly ex ten-ding :u pedestal: or bracket? 28% equipped with 'a-hox o'rbea ring ee rorzthe aneasrme thes auxiliary; ffanie' will" thus be partlyi'susiiendedi The auxiliaz'y frame G is located within that portion of the traction 'wheel B which is not provided with spokes,

as is obviously necessary in order to permit rotation of the wheel to take place. The rim 22. of the traction wheel is provided with a circumferential flange 30 of ample width to brace and reinforce that side of the wheel which is not provided with spokes and also to serve as a mud guard for the mechanism supported by the auxiliary frame. The latter is equipped with a platform 31 on which is supported a motor M of the internal combustion or any other suitable and desirable type, said motor having been shown as being equipped with a crank shaft 32 having a fly wheel 33'and 'a'worm 34, the latter meshing with a worm gear 35 on a counter shaft 36, the latter having a pinion 37 meshing with a'spurwheel 38 on the axle'25 to which motion will in this manner be transmitted from the source of power. It isobvious that reversing gears, speed gears and clutch means for interrupting the motion when desired are to be provided for, but such devices being well known and in general use, it is not considered necessary to illustrate .or particularly describe the same.

The crank shaft 32 has been'shown as being provided with a pulley 39 from which motion is transmitted by a belt 40 to a shaft 41 carrying a fan 42 forcooling the radiator 43, it being, however, understood that said radiator may be dispensed with when an air cooled engine is used. The gasolene tank 44 is supported on the platform of the auxiliary frame C.

The side member 15 of the main frame is provided with bearings 45 for a counter shaft 46 which may be driven by means of any well known form of transmission 47 fromthe crank shaft of the engine. From the counter shaft 46 motion may be transmitted in any convenient manner'to stationary machinery of any kind that it may be desired to utilize the motor for driving when the device is not used as a traction engine.

It; is obvious that in the transmission of power from the counter shaft to the ma- 'chinery to be driven, suitable clutch means should be included when desired.

The main frame is provided at its forward end with an upwardly and forwardly extending arcuate bracket 48 carrying a swiveled fork 49 which supports the steering wheel 50. Thefork49 carries a worm gear 51 meshing with a worm 52 on a steeringrod 53, which latter is partly supported bn a lbracket'54, said steering rod including a universal joint 55 and a hand wheel 56, which latter is within convenient reach of the operator. The bracket 54 which supports the steering rodrisesfrom the bearing members 26 in which the axle is supported for rotation, said bracket consisting of an inverted yoke that straddles the traction wheel over which the steering rod must ob viously be carried.

From the foregoing description taken in connection with the drawings hereto annexed, the operation and advantages of this invention' will be readily understood. It will be seen that the traction wheel is made of ample width to enable it to support the frame of the machine without danger of tilting or upsetting. At the same time a traction engine embodying the invention may be constructed of moderate size, en-

abling it to be operated between rows of 'connecting the hub with the rim adjacent to one edge of the latter, an axle fixed in. the hub, a mainframe having side members, and pedestals rising from the side members and having bearings wherein the axle is supported for rotation.

2. In a traction engine, a traction wheel having a hub and a rim, the latter being of a width materially exceeding that of the hub, an axle fixed in the hub, a main frame suspended from the axle, and an auxiliary frame partly supported on the main frame and artly suspended from the axle, said auxillary frame being housed within the rim of the wheel. r 1 p I 3. In a traction engine, a traction Wheel having a hub, an axle fixed in the hub, a

main frame suspended from the axle, an

auxiliary frame partly supported on the mainframe and partly suspended from the axle, said auxiliary frame being housed within the rim of'the traction wheel, anda motorgand transmission mechanism supported on the auxiliary frame to drive the main frame suspended from the axle, an'

auxiliary frame housed withintherim of.

the traction wheel, clamp means connecting "one sideof the auxiliary frame with the main frame, suspending means connecting, the other side of the'auxiliary frame with the axle, a motor supported on the auxiliary frame, and means for transmitting'motion from the motor to the traction wheel.

5. In atraction engine, ajtractionwheel;

having a hub, an axle fixed in the hub, a main frame suspended from the axle, an auxiliary frame suspended from the axle and also connected with the main frame, said auxiliary frame being located Within the rim of the traction Wheel, a motor supported on the auxiliary frame, means for transmitting motion from the motor to the traction Wheel, a steering Wheel at the front end of the frame, a seat at the rear end of 10 the frame, and a steering rod guided and supported above the traction Wheel, said steering rod including a universal joint.

In testimony whereof I aflix my signature.
